This paper describes an automated image restoration algorithm. The technique is based on the Stockwell transform (ST) and its discrete version, the discrete orthonormal Stockwell ...
This paper proposes a self-authentication scheme for color images, using a fragile data hiding method based on the Discrete Pascal Transform (DPT). The main contribution of this wo...
In this paper we study the e ects of transmission noise on xed-length coded wavelet coe cients. We extend our previous work on maximum a posteriori detectors 1] to include interbi...

This paper describes an expectation-maximization (EM) algorithm for wavelet-based image restoration (deconvolution). The observed image is assumed to be a convolved (e.g., blurred...
–—Wavelet expansions and wavelet transforms have proven to be very efficient and effective in analyzing a very wide class of signals and phenomena. Wavelet expansion allows a m...
